“ Despite all of the time he spent in Big Heart's, Wilson had never come to understand the social lives of Indians. He did not know that, in the Indian world, there is not much social difference between a rich Indian and a poor one. Generally speaking, Indian is Indian. A few who gain wealth and power as lawyers, businessmen, artists, or doctors may marry white people and keep only white friends, but generally Indians of different classes interact freely with one another. Most unemployed or working poor, some with good jobs and steady incomes, but all mixing together. Wilson also did not realize how tribal distinctions were much more important than economic ones. The rich and poor Spokanes may hang out together, but that doesn't necessarily mean the Spokanes are friendly with the Lakota or Navajo or any other tribe. The Sioux still distrust the Crow because they served as scouts for Custer. Hardly anybody likes the Pawnee. Most important, though, Wilson did not understand that the white people who pretend to be Indian are gently teased, ignored, plainly ridiculed, or beaten, depending on their degree of whiteness. ”
